Fable II is supposed to go for $20 if you download it on the Xbox 360. But, less than two weeks before the release of Fable III, it's now free on the Xbox Live Marketplace. [UPDATE: Not working for everyone.]
Smells like a marketing stunt and a bargain. Got 7GB free? Then go for it.
NOTE: We know that some of you aren't getting this to work. On our end we're seeing mixed results as well, but do have a free download in progress.
We're checking with Microsoft to find out if they goofed or if their prices really are that insane. [PIC]
